I recently got Windows XP 64 bit and for some reason when i move the eq screen itself to another monitor the cpu goes up to 50 % and the toon gets very laggy as well as my mouse at half speed as well. I did not have this problem on 32 bit xp at all. I have the latest ATI drivers. Even if part of the EQ screen is on the other monitor it does this. Could it be something other than the graphics driver? I also upgraded to intel pentium duel core 2 8500 processor as well. Anyone have any ideas at all ? The service pack 3 fix for multiple cores isnt for windows xp 64 btw.
